My wife and I would like to find out what it would take to get the pool @ my mothers house in usable shape. It's 35 years old, inground, approx 15 x 30, its some sort of gunnite pool with some sort of marble dust finish.

The pool is very green, hasnt been used since the early 90's. It does not appear to leak. Where do I start?? Do I try to run the equipment? Clean the water? Pump the pool dry and start over? Any help would be great.
